[SOLVED] How to recover from boot drive failure

[Floso]

Hello,

I am thinking about installing proxmox VE on a server with a small boot SSD for the OS itself and a nvme ZFS mirror for the VMs.
What I would like to ask about is how I can restore the server in case of a boot drive failure. I can probably import the ZFS pool but will the VMs then just show up in the Webinterface without any hassle? I don't think so since I believe I read somewhere that the VM configs are stored on the boot drive. Is it maybe enough to backup /etc on a daily basis via a crontab and in case of a failure restore it onto the new install?

Thanks

Probably, most of the time. But why not use (proper 3-2-1) backups that allow you to recover not only from a boot drive failure but also from other hardware failures, fires and (human) mistakes (regardless of the used hardware)?

Thanks for the answer! I am still creating automatic backups of my VMs and store them on my NAS. Only problem is that I want to virtualize TrueNAS in proxmox so I don't have access to those backups in case of a bootdrive failure. In every other error case I could restore backups from the cloud or from the NAS.

Actually I will probably be able to recover the backups from TrueNAS even without all that. I can just mount the TrueNAS zpool and copy the backups to the new drive.
